OPERATION
CAUTION:
•
Always insert the battery cartridge all the way
until it locks in place. If you can see the red part
on the upper side of the button, it is not locked
completely. Insert it fully until the red part cannot
be seen. If not, it may accidentally fall out of the
tool, causing injury to you or someone around
you.
Hold the tool firmly. Place the drill bit on the workpiece
or place the socket over the bolt or nut and turn the tool
on. For fastening operation, release the switch trigger
after the proper fastening time.
Drilling in wood
When drilling in wood, the best results are obtained
with wood drills equipped with a guide screw. The guide
screw makes drilling easier by pulling the bit into the
workpiece.
CAUTION:
•
Pressing excessively on the tool will not speed
up the drilling. In fact, this excessive pressure
will only serve to damage the tip of your bit,
decrease the tool performance and shorten the
service life of the tool.
•
There is a tremendous force exerted on the tool/
bit at the time of hole break through. Hold the
tool firmly and exert care when the bit begins to
break through the workpiece.
•
A stuck bit can be removed simply by setting
the reversing switch to reverse rotation in order
to back out. However, the tool may back out
abruptly if you do not hold it firmly.
•
Always secure small workpieces in a vise or
similar hold-down device.
•
If the tool is operated continuously until the
battery cartridge has discharged, allow the tool
to rest for 15 minutes before proceeding with a
fresh battery.
Fastening torque
The proper fastening torque may differ depending upon
the kind or size of the bolt, the material of the workpiece
to be fastened, etc. The relation between fastening
torque and fastening time is shown in the figures.
